- @dbess340 Yeah, I'd just go and get what's out there today. I think SRM is overpriced at this point, hence why I'd go PT/Quarq/P2M/Stages. #, 5 hours ago
- @mikeportman Haha...beautiful place! And with an awesome track right there too! #, 5 hours ago
- @dbess340 The Quarq, Power2Max both do. Albeit estimated. But there's virtually no training benefit today. #, 5 hours ago
- @dbess340 They do not at this time. #, 6 hours ago

Read my Top 25 most useful posts.
It turns our I’ve written a fair bit of stuff over the past few years – and after it disappears from my front page, a lot of it never really sees the light of day again without Google’ing skillz. Or a photographic memory…which I don’t have. I’ve taken a look back and found stuff that…continues to find a trickle of readers via web searches or forum links.
Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
